@IKTime no lmao. She doesn't saying she has more chakra, Obito says that Narutos chakra COMBINED with hers is enough. Not Sakuras alone.
She gets blitzed by casual Madara 0 diff, then tries to punch him which Madara nonchalantly blocks with limbo. Sasuke and Kaguya both consider Sakura useless and not worth Kaguyas attention. Sakura herself says she can't come even close to Sasuke or exchange blows with him
These makes her scaling to Madaras or Kaguyas speed in any way completely impossible.
Hell base Sakura legit gets so scared of 1r juubidara she forgot to breath, and got later perception blitzed by GT 1r juubidara.
Her breaking Kaguyas horn is an alright physical feat, ASSUMING SHE'S NOT RESOLVE AMPED. But even that benefit of the doubt would at best meani she's basically just a heavy hitting snail.
Sakura has basically 0 speed feats beyond base pre-Hagoromo Naruto level and 0 hax to make up for it. She can punch hard but with her mediocre speed she's not going to be landing full power shots on anyone kcm1 Naruto level or above. This also makes it impossible for her to counter majority of OP hax. Anything above low-end mid Kage is purely wank.
